Procedure to preserve antigens of Entamoeba histolytica without enzymatic inhibitors

摘要

The invention relates methods of determining Entamoeba histolytica antigenic reference patterns of proteins recognized by sera from patients having amebic liver abscesses, patients having intestinal amebiasis and patients negative for any amebic disease and methods using these antigenic reference patterns for aiding in the differential diagnosis of a patient with amebic liver abscesses or intestinal ambiasis by detecting the presence of antibodies in a sample of human serum which bind to Entamoeba histolytica proteins identified in the antigenic reference patterns.
